Driving device, electronic apparatus provided with the driving device, and driving device control method

A driving device, comprising:

• a motor;
• a plurality of electromagnetic clutches respectively installed in a power delivery route between the motor and a plurality of driven bodies, each of the electromagnetic clutches including an input member driven by the motor, an armature connected to the input member so as to rotate together with the input member, a rotor arranged in a coaxial relationship with the armature, an output member interconnecting the rotor and each of the driven bodies so as to rotate together and an exciting coil configured to generate a magnetic force;
• a motor control unit configured to control an operation of the motor;
• and
• a clutch control unit configured to, by controlling energization and de-energization of the exciting coil of each of the electromagnetic clutches, selectively switch each of the electromagnetic clutches to a connected state in which the armature and the rotor are connected to each other and a cutoff state in which the connection of the armature and the rotor is cut off,
• wherein, when the motor control unit stops the motor from an operating state, the clutch control unit controls the energization and de-energization of the exciting coil of each of the electromagnetic clutches so as to switch one or more but not all of the electromagnetic clutches to the cutoff state while keeping the remaining electromagnetic clutches in the connected state.
